FIELD OF THE INVENTION

The present invention relates to field of communications and generallyto transmission of radio signals and more particularly to transmissionof radio signals minimizing sidebands.

BACKGROUND OF THE INVENTION

The known modulation apparatus and modulation processes are believed tocontain all the information in sidebands and require finite bandwidthwhich is proportionate to highest signal frequency. The technique isuniversally applicable to amplitude modulation, frequency modulation,phase modulation, on/off keying and many combinations of these processesall require side bands to carry the information. With all knownmodulation processes require higher modulated carrier bandwidth, inproportion to highest modulating signal frequency and highest data rate.The RF carrier is an electromagnetic wave having characteristic that canbe modified from known reference according to modulating signal.Modulator is a device where the carrier and modulating signals cometogether to change carrier frequency properties to create modulatedcarrier.

Modulation process is known to continuously alter one or more sine wavecharacteristics of the carrier wave like amplitude, phase, frequency andother individually or in combinations. Such processes invariably produceintermodulation products resulting as sidebands, in modulated carrierwave output, which (side bands) are believed to carry all the signalinformation. These sidebands vary in amplitude and their bandwidthdepending on various factors including type of modulation, type andquality of signal, reliability factors, carrier frequency, modulatingsignal bandwidth and others.

Sidebands in prior art are generally on both sides of the carrier knownas upper side band and Lower side band and carry all the information.Some modulation systems transmit carrier with one sideband suppressedcompletely or partially to conserve transmission bandwidth.

Modulator having more than one carrier waves are known for carryinglarge data and wide band signals. Modulating signal may be of digitaland/or analog types such as voice, picture, text, data with wide varietyof raw information, coded, multiplexed, compressed, encrypted orprocessed. Modulation process and devices known in prior art always havean associated demodulation process known as demodulator. Demodulation isknown as a process of retrieving the original information from modulatedcarrier wave. Effect of demodulation apparatus and process is alwaysexactly complimentary to the modulation process, separating theinformation and carrier wave, demodulators will have decoder,demultiplexer, decompressing, de-encrypting and other processes tofaithfully recover information in original form.

In the prior art all known types of modulation processes consumespectrum in side bands with bandwidth according to highest frequency ofmodulating signal, making available only finite numbers of frequenciesfor transmission of information using air waves. This availability oflimited numbers of frequencies has resulted in government regulating theresource. The regulation also ensures non-conflicting and fair use ofthis limited resource. Demand far outstrips the supply in numbers ofmodulating frequencies available for commercial and public use thus denyit to some.

In view of the above facts, there is a need in the art for moreefficient use of available spectrum to convey maximum information whileconsuming minimum bandwidth of the spectrum for each Radio Frequencymodulating signal. The need for improvement in process to conservespectrum bandwidth using a variety of modulation types in various modesof radio frequency communication system is very much there.

OBJECT OF THE INVENTION

An object of the present invention is to produce modulated sine wavecarrier with zero side bands for transmission of signals and use sinewave carrier frequency itself to carry the information.

Another object of the present invention is to make carrier frequencyitself to carry all the information, to reduce the bandwidth requirementin communication system to zero.

Another object of the present invention is to remove completely allsidebands produced during modulation process to zero and make it highlyspectrally efficient.

FIGS. 38a and 38b illustrate a conventional AM peak detector and itseffect on peak value of carrier cycle.

CONCEPTUAL WORKING OF INVENTION DRAWINGS (FIG. 6A) AND (FIG. 11A)

FIGS. 38a and 38b show that only the peak value of carrier cycle is usedby the AM peak detector. The figure is a poorly implemented peakdetector for highlighting modulated and detected signal. With frequencyratio of 10 to one is used in the figure and there are 10 cycle of thecarrier cycle during one cycle of the signal. The detected signalwaveform is showing positive spikes reaching the peak level of modulatedcarrier cycles and then drooping a bit. Deliberately the filter shown isof poor quality to show drooping of detected signal and peaks are risingto next peak of carrier. This shows that the detector is only taking thepeak envelop value of the carrier cycles and rest of the sine cycle ofthe modulated carrier does not contribute any value to output.

This above example shows that each cycle of carrier is carrying its peakamplitude value which can be treated as sample value of modulatingsignal. It shows that peak value of each sine wave cycle of carrier waveacts as sample value of modulating signal and just the peak value ofeach carrier cycle is needs to reproduce original signal as long as thecarrier frequency is sufficiently higher. For all practical purposes abetter and appropriate filter needs to be used.

Keeping above example in mind following explanation in detail of thewaveforms shown in (FIG. 6A) with (FIG. 11A) in accordance with anembodiment of the present invention will assist those skilled in the artto understand the working of invention. Which claims by forcing eachcomplete sine wave cycle of the carrier to follow pure sine wavefunction, and by defining amplitude vector at beginning of the sinecycle at a zero voltage crossing point, it can carry large amount ofinformation or data by the carrier frequency itself without generatingany side bands.

The embodiment of FIG. 6A uses AES3 digital audio signals and a littleunderstanding of digital signal format of AES3 format can assist thoseskilled in the art. AES3 is a 24 bit uncompressed stereo audio digitalformat allowing encoding the clock and the data together using, biphasemark code (BMC). This coding is polarity immune and every transition inlevel from “0 to 1” or from “1 to 0” represents a “logic 1”, steadystate either at high level or low level represents a “logic 0”. Moredetails on AES3 can be found at official AES site or at“https://en.wikipedia.org>wiki>AES3”

In an embodiment of the invented transmission process we generate onepure sine wave cycle at carrier frequency starting at zero crossingpoint and ending at another zero-crossing point for every transition.Between the transitions we generate zero voltage cycles which representno transition in the modulating signal. Or to say we are eithergenerating a pure sine wave cycle or generating nothing ensuring thereare no side bands produced.

The AES3 signal waveform is shown in (FIG. 6A2) with its bit clock shownfor reference only in (FIG. 6A1). The actual data value is marked in(FIG. 6A3) which is coinciding with transitions. In accordance with anembodiment of the present invention, steps of converting each transitionin input signal in to one 0° to 360° pure sine wave cycle, starting atzero crossing point and ending at subsequent zero crossing point at thecarrier frequency are shown in FIG. 6A4 to FIG. 6A8.

Data edge extractions waveform is shown in (FIG. 6A4). Carrier frequencyclock is shown in (FIG. 6A5), which provides timing information togenerate one cycle gate pulse corresponding to each transition in signalas shown in (FIG. 6A6). This pulse is used further to generate a groundcentred square wave cycle, having half positive going and half negativegoing cycle. This ground centred wave cycle of (FIG. 6A7) is furtherpassed through a filter to generate one pure sine wave cycle. (FIG. 6A8)shows the modulated sinusoidal carrier wave with zero side bands. Sinewave cycle (pure) of (FIG. 6A8) achieves the inventive step of startingcarrier sine wave cycle at zero voltage crossing point and ends thecarrier cycle at zero crossing point, only after completing one 0° to360° pure sine wave cycle at the carrier frequency. Amplitude of thesine cycle is defined at the beginning of sine cycle. It uses zerovoltage cycles for remaining time.

Thus, generated waveform of (FIG. 6A9) is similar to an “amplitudemodulated wave form” with only two amplitude value, one is the amplitudeof generated sine wave cycle and other being zero voltage cycle withzero amplitude. The sine wave cycles generated are configured togenerate only pure carrier sine wave cycles with zero side bands. It isimmaterial if the sine wave cycle starts with opposite polarity, as longas the cycle is a full sine wave cycle at carrier frequency as perappended claims. This invented method/system only generate modulatedsine wave carrier cycles and does not generate any side bands is shownin (FIG. 6A9) which carries all the signal information within carrierfrequency itself.

The key inventive step is to start each individual carrier cycle withits one or more properties defined, in proportion to modulating signalat cycle starting zero crossing point and end the cycle at consecutivezero crossing point on completion of one pure sine wave cycle, in acycle by cycle generation process. Modulating signals can changeproperty of carrier wave sine cycle only at the cycle start zerocrossing point, for each complete sine wave cycle of the carrier.Generation of each sine wave cycle can only start with its propertiesdefined at start of each cycle and once the sine wave cycle generationstarts, it's property cannot be changed by modulating signal during thecycle. In the invented steps zero voltage cycles are valid cycles.

The invented transmission system does not have any side bands and thusit does not need any channel bandwidth, its maximum bandwidth capacityto carry wide band signals is much higher. The maximum bandwidthcapacity of transmission system to carry wide band signals is alsoproportionate to the carrier frequency.

Modulating signal bandwidth capacity of the invented transmission systemfor faithful reception can be derived from nyquest theorem. The NyquistSampling Theorem states that: an analog signal waveform may be uniquelyreconstructed, without error, from samples taken at equal timeintervals. The sampling rate must be equal to, or greater than, twicethe highest frequency component in the analog signal.

The receive system wave forms are shown in (FIG. 11A) which arecomplimentary to (FIG. 6A) and show how to recover original modulatingsignal from the modulated sinusoidal carrier waves with zero side bands.The receive system working looks like a conventional receiver as far asthe steps like front end, AGC and associated heterodyne process, butdiffer in their optimisation for “side bands free modulated signal”. Inthe invented method, the band width requirement in all these stages isas narrow as practically possible to pass only the pure carrierfrequency and may be application dependent.

In a receiver embodiment of the present invention, amplitude of eachsinusoidal carrier wave cycle (FIG. 11A2), received carries 1 bit data,representing transition in the original modulating signal. This one bitsignal is recovered by slicing the selected, filtered, amplifiedmodulated sinusoidal carrier waves with zero side bands and generate alogic pulse, representing the transition. This square pulse is used totoggle a flip flop to produce the original AES3 wave form shown in FIG.11A7.

Different modulation types but not limited to listed here can benefit inreduction of substantial bandwidth requirement using invented method isare:

PM Phase Phase Shift Keying in conventional term is achieving modulationmodulation by changing the phase angle of the carrier sine or wave inresponse to modulating signals. This type of PSK modulation has manyvariants and one of the most Phase shift popularly known being QPSK(Quadrature Phase Shift Keying Keying). All the variants need bandwidthin proportion to highest signal/data frequency and have evolved overtime for specific applications with advantages. All variants of PSKeither alone or in combination with other properties like amplitude orfrequency can benefit from method and system of the present invention.Variants include but not limited to: -BPSK (binary phase- shift keying),(DBPSK (differential BPSK). DPSK (differential phase-shift keying), QPSK(Quadrature Phase Shift Keying), DQPSK (differential phase-shiftkeying), QAM (quadrature amplitude modulation), OFDM modulation, OFDMwith QPSK. OQPSK also known as SQPSK (Offset Quadrature Phase ShiftKeying), BPSK or PRK, phase reversal keying, or 2PSK, SOQPSK(shaped-offset QPSK), Continuous phase modulation (CPM) and many morefine variants of these. OOK (ASK) Amplitude-shift keying is the mostbasic and one of On Off the earliest modulation schemes. It basicallyswitches ON Keying or OFF the basic carrier itself under control of themodulating signal which is mostly digital or manual. Variants includebut not limited to: - ASK Amplitude Shift Keying, it is frequently usedin optical communication systems. With addition phase shift to it,becomes APSK. AM Amplitude modulation is quite common and is Amplitudeimplemented by variation of the carrier wave amplitude in Modulationresponse to modulating signal. Variants include but not limited to: -double side band, Single Side band, Vestigial side band, suppressedcarrier and variants of this. In addition, its combinations with PhaseShift and frequency shift are also there. FM FM is a method oftransferring information by changing frequency in proportion to themodulating signal. It is widely used in broadcasting and othercommunication systems independently. FM can also be combined with AM andother modulation processes to conserve transmission bandwidth. Variantsinclude but not limited to: Frequency Modulation, FSK is another form offrequency modulation. Multiple frequency shift keying and minimum shiftkeying are the other variants of FM with additional parameters. MFSKsystem is dual-tone multi-frequency (DTMF), OFDM is a frequency-divisionmultiplexing (FDM), QPSK, and others QAM and Phase Modulation incombination to amplitude and other frequency are used in modern digitalcommunication combinations systems. Its most popular variant is with itscombination with amplitude modulation known as QAM and its variants.The present invention has various advantages. The system and method canprovide solution for transmission of data and high bandwidth signalsusing narrow channel band width up to zero hertz. Another advantageincludes production of zero sidebands, which results in carrierfrequency itself carrying the vast amount of data and other signalsoffering better utilization of spectrum bandwidth. In other words, moreinformation can be transmitted using limited spectrum up to a singlefrequency. Another advantage of the invention is reduction in noisedensity for the received carrier signals. The advantage will majorlydepend on use of technique to limit the bandwidth of received channel inpractice to below 100 Hz or 10 Hz. For a received device bandwidthreduction from 10 KHz to 100 Hz will provide a noise floor reduction ofabout 40 dB.
